I updated my programer h&s blackmaxx with the new update about a week ago. I have been having problems doing the relearn process for trans. My eng revs to almost redline when shifting into 3rd and 4th gear while jerking in and out of gears and then gets stuck in 4th gear. After a few trys I get same results everytime and get a check eng light and wrench light. I am doing something wrong? Or is it a bad update file? Is anyone having a problem like this, or can advise me on what to do.

I would make sure that the new program is showing in your settings, if it is try reloading the program and if same thing happens call H&S. I had my truck do that before i loaded the newest program. after loading new program and 600 miles later no problem. Hope this helps.

ive tried reloading it three times, even went back to stock, cycle the shifter and reloaded the program and tranny still shifts like ****. never had this problem before until i uploaded the new update. would like to get some input from H&S Rep. Ive called them twice today and no answer. im stuck now on going thru the pain of returning my truck to stock and having ford look at it.

ok, took my truck to ford, the told me that the valve body in the trans went out. said it was odd for my truck since i only have 10,000 miles on it, and they usually see it in trucks with over 50,000 miles, not one truck have they seen like that with low miles.

Yes it was covered under warranty, thank god. i just got my truck back after three weeks. the problem was " the whole trans **** its self" torque coverter clutches were seized, all the solenoids were damgaged, solenoid pumps, (fwd, direct, rev, etc) were damgage. tons of shavinging. so whatever caused it got me a new transmission. the reason why i waited three weeks is cause the trans were on backorder throught the US.

[QUOTE=mpowerstroke;2374556]did your mini maxx cause the problem?
my truck shifts hard when im in the hot setting and punch it, you have the same problem.

Sorry to post this question but since your on line--Are you happy with your MiniMax? Diesel shop is pushing the H & S even though they also sale Spartan. What are your thoughts as I've never had custom tunes in my trucks and want to get the best with no BS problems.
